D, E, from the middle of the face to the margin of the lips.
From the auditory canal, G, to the maxillary spine, F, is the same distance as from this point to the margins of the lips, E, or, better, to the end of the teeth.
Fig. 111.—The Same Figure as [Fig. 110], on which we have marked by Similar Lines the Principal Measurements which correspond thereto.
Distance which separates one of the orbital arches from that of the opposite side, and the dimensions which equal it; distance which separates the auditory meatus from the maxillary spine, and the dimensions which equal it; distance which separates one maxillary spine from that of the opposite side, and the dimensions which equal it; distance which separates the lip of one side from that of the opposite, and the dimensions which equal it.[65]

The line G, C, from the auditory meatus to the nape, is equal to the sixth of the head, 10 centimetres; the line A, G, from the orbital arch to the auditory meatus, is a little longer, and measures 12 centimetres.
The distance F, I, comprised between the maxillary spines, is 18 centimetres.
It is equal to:
